Description

technical field [0001] The invention relates to the technical field of dust collector control, in particular to an optimized energy-saving dust removal control method and system for a bag pulse dust collector. Background technique [0002] Dusty industrial waste gas may be generated from mechanical processes such as crushing, screening, conveying, and blasting of solid substances, or from processes such as combustion, high-temperature melting, and chemical reactions. Dust collectors are widely used to control the dust and fumes that have been generated. According to the collection mechanism, dust collectors can be divided into mechanical dust collectors, electric dust collectors, filter dust collectors and washing dust collectors. The mechanical dust collector relies on mechanical force to remove dust particles from the airflow. It has a simple structure, low equipment and operating costs, but the dust removal efficiency is not high. Electrostatic precipitators use electro...
